ELECTRIC-CONDIJ'IT FITTING.

Specification of Letters Patent.

Patented Aug. 6, 1912.

To all whom it may concern:

Be it known that 'we, CARL H. BissELL and FLOYD SMITH, of Syracuse, inthe county of Onondaga and State of New York, have invented a certainnew and useful Electric- Gonduit Fitting, of Which'the following is aspecification.

Our invention relates to electric conduit fittings, and has foritsobject the production of such a fitting which can be adapted to standardcommercial electrical appliances of difi crent makes and sizes, and itconsists in the combinations and constructions here inafter set forthand claimed.

In describing this invention, reference is had to the accompanyingdrawing in which like characters designate corresponding parts in allthe views.

Figure 1 is a top plan of one form of our electric conduit fitting, thecover being open and an electrical appliance being mounted on one end ofthe fitting. Fig. 2 is a plan of an end portion of the fitting. F 3 is asectional view on the plane of line AA,

Fig. 2, parts being included in Fig.3 not shown in Fig. 2. Fig. 4, is aView similar to Fig. 3, showing an electrical appliance supported by thefitting. Fig. 5 is a detail View of the ring for supporting theappliance.

1 is the electric conduit fitting comprising a body or box having anopen top, and a cover 2 for such top, and extensions 3 at itsoppositeends. The body is preferably elongated and is provided withsuitable nipples 4 extending from its sides by which connec tion is madewith conduits, and also with other nipples 5 extending from its ends bymeans of which connection is made with other conduits. The nipples i arepref erably formed funnel-sl1ape at 6 at their bases for permittingspreading ofthe wires within the body and avoiding sharp bends in thewires. The body is also provided with means, as a plate 7 locatedtherein for supporting electrical appliances, as cutouts a connected tothe wires within the body. This outs of diiierent sizes and makes.

plate is removable thropagh the open top and is of substantially the smsize as the opening in the top and is provided with a plurality ofslots 8 for receiving the fastening means as screws associated withelectrical appliances or cutouts. The-slots are employed instead ofordinary holes in order to permit the plate to support commercial cut-As seen in Figs. 3 and i, the. top of each extension 3 is inclinedtoward the end of the body and is formed with a circular opening notches10 for a purpose to be explained. 11 is aplate formed with a centralopening and having its outer margin seated on the margin of the topwall, the plate 11 partly closing the opening 9. As the opening 9 iscircular, the plate 11 is in the form of a ring. The ring 11 ispreferably formed of sheet metal and is provided with shoulders 12struck therefrom. and spaced apart for en'- tering two of the notches10. The ring 11 is also formed with a diametrically extending bridge 13having a plurality of pairs of holes 14 near its ends and locateddifferent distances from the center of the ring, the

holes ofeacliv pair being located diametrically opposite to each other.The central portion of the bridge is usually depressed and formed'withan opening 15 located at the center of the ring and designed to receivea screw 16 which threads into a support as a bar 17 extending from oneside wall of the extension 3 to the other, crosswise. of the opening. 7

18 is an electrical appliance as a rotary switch mountedon the ring'andsecured thereto by a pair of screws 19 which enter one of the pairs ofholes 14. By means of the ring, the fitting can. be adapted to differentsizes of switches, as for a large switch, a ring of smaller area isemployed than when a smaller'switch is used, and by reason of the holes14 the ring is adapted to receive the screws 19 of the standard makes ofswitchesnowon the market, said screws being arranged in holes as 20 inthe appliance, and in different makes of switches these holes are spaceddifferent distances apart. fittings for different makes of switches, theholes 14 are so located from the center of the ring that one pairthereof will register with the openings-20 for the screws as 19 of thevarious commercial switches.

In the various commercial switches the indicator openings which showwhether or not the switch is on or ofl' do not always bear the samerelative position, and therefore for the purpose of permitting theTherefore, "in order to adapt the arrangement of the various commercialbe conveniently seen, the ring is adjustable about its axis and. duringsuch adjustment the shoulders 19, on the ring 11 are brought intoposition to enter predetermined notches 10.

In the use of the conduit fitting here illus-.

tures of our electric conduit fitting are claimed in our divisionalapplication, Sr. No. 684,370, filed Mar. 18, 1912.

What We claim is 1. The combination of an electric conduit lit-tingcomprising a hollow body having means for connection With a conduit, anda circular opening in one Wall the r-cot, the edge of the Wall aroundthe opening being formed with notches, a ring resting on the margin ofthe Wall around said opening and partly covering the opening, the ringbeing formed with means for engaging the notched edge of such margin,additional means for holding the ring in position, and an electricalappliance mounted on the ring, substantially as and for the purposedescribed.

2. The combination of an electric conduit fitting comprising a hollowbody having means for connection with a conduit, and a circular openingin one Wall thereof, the edge of the Wall around said openingjoeingformedl'with notches, a ring resting on the margin of the wall aroundsaid opening, and partly covering the opening, the ring being formed.with shoulders spaced apart for engaging the notched edge of said margin, the ring being adjustable about its axis for bringing the shouldersinto differentnotches, the ring also having a diametrically extendingbridge piece, means extending through the bridge piece for clamping thering in position, and ail-electrical appliance mounted on the ring,substantially as and for the purpose specified.

In testimony whereof, We have hereunto signed our names in the presenceof two at testing witnesses, at Syracuse, in the county of Onondaga, inthe State of New York,
